The PuroBot Ultra is for owners who want camera health logs and sealed waste bags they rarely touch. It is expensive, deep at 32.2 inches, and Cats.com found larger cats avoided it. Several features sit behind a subscription.

Leo's Loo Too is a large drum box that testers credit with strong odor control thanks to its UV light and carbon filter. It is pricey and bulky, and one Rover tester's cat hissed at the cycle noise and avoided it. Keep a backup box until a nervous cat adjusts.

What reviewers found

Petkit PuroBot Ultra

  • Cats.com (3.8/5): Six weeks of testing: scooping and sealing worked well, but larger cats would not use it, face recognition sometimes confused two cats, bags tore easily and litter leaked around the edges. Source
  • Catster (4.9/5): Six weeks with one cat: no litter smell noticed, and the camera helped the tester spot a period of constipation; filling it with litter was awkward and there is no low litter alert. Source

Smarty Pear Leo's Loo Too

  • Rover: No noticeable drawer smell after an 11 day absence and the app identified a cat by weight; one cat kept hissing at the cycle and avoided the box. Source
  • NBC Select: Used for over six months with one cat in a New York City apartment; the drum stopped when the cat approached, and the drawer filled in about 7 to 9 days. Source
  • The Gadgeteer: Odor was much lower than a standard box and the cat adjusted within hours; weight sensing may not work on carpet or soft floors. Source
